hey, i've just bought this phone
is it normal to lose 6% of battery charge in 20miuntes (with conected wifi, exploring store and mid brightness) ???
or losing about 40% of battery in a half day of normal usage good for this phone???
is my lumia's battery healthy??

Lumia 830 is well designed with aluminium with back as plastic . It feels good in hand with the width , Good camera especially Low light Pictures are great .
Apps run smoothly & multi-tasking is good , but games like Asphalt are not recommended for this phone . Front camera is bad as having 0.9MP due to rear camera 10 MP which is good at this price .

kgautham, 05 Sep 2015do really lumia 830 support 4g
Yes 100%, coz i'm using Airtel 4G, it shows 4G and speed is 10Mbps+.
Enquired why it is low in chennai when i get 20mbps+ in bangalore, Airtel exec told me that it is a soft launch in chennai.
You need to have latest update Microsoft which will enable 4G.
Happiest owner of Lumia 830.
